| 1 | Parity violation in chiral structure creation under femtosecond laser irradiation in silica glass?显示文摘The paper addresses the creation of circular optical properties from a femtosecond laser light beam with a linear polarization in an achiral material(glass)under an orthogonal incidence.In this situation,all aspects of the experiment are achiral and therefore should not give rise to chiral property creation.From that observation,we propose an interpretation that involves the action of a light-induced torque on the matter carrying a light-induced dielectric moment.We found that a direct current(DC)electric field could be produced in the lattice by the femtosecond laser in our conditions and that a non-collinear dielectric moment is created by a nonlinear effect between the DC electric field and the stress field due to the transformation of the material.We reveal that it is possible to break the chiral symmetry of glass using an intense,ultrashort laser light pulse. | Bertrand Poumellec Matthieu Lancry Rudy Desmarchelier Evelyne Hervé Bernard Bourguignon | 2016 | Light(Science & Applications)2016，5，1： | 2 |

| 6 | 飞秒激光调控非线性光学晶体和周期性纳米结构取向显示文摘通过高频(100~500 kHz)飞秒激光直写可在组成是Li_(2)O-Nb_(2)O_(5)-SiO_(2)的玻璃内部同时控制纳米非线性光学晶体和周期结构取向。该周期结构为发生纳米尺度相分离的晶态和非晶态交替结构,并可通过激光偏振方向来控制朝向。随着激光注入能量的增加出现了3个改性区间:低能量下改性非晶态,对氢氟酸(HF)的刻蚀速度高于玻璃基底;中能量下纳米晶体极轴趋向和激光偏振方向垂直,随着激光频率的提高,获得此区间的脉冲能量窗口急剧减小;高能量下微米晶粒,并且晶体的产生受写入模式影响(写入方向和激光偏振方向的夹角)。该研究发现有利于理解超快激光-物质相互作用和制备三维光器件。 | 曹晶 Lancry Matthieu Brisset François Poumellec Bertrand | 2022 | 激光与光电子学进展2022，59，15： | 1 |
| 7 | Tailoring chiral optical properties by femtosecond laser direct writing in silica显示文摘An object that possesses chirality,that is,having its mirror image not overlayed on itself by rotation and translation,can provide a different optical response to a left-or right-handed circular polarized light.Chiral nanostructures may exhibit polarization-selective optical properties that can be controlled for micro-to-nano optical element engineering.An attractive way to induce such complex nanostructures in three-dimension in glass is femtosecond laser direct writing.However,the mechanism of femtosecond laser induced chirality remains to be unveiled due to complex physical and chemical processes occurring during the ultrashort light-matter interaction.Here,a phenomenological model is proposed and is built on two-layers phase shifters to account for this laser-induced optical chirality in an initially achiral material(silica glass).This model is based on the observation that femtosecond laser induced nanogratings own two principal contributions to its aggregate birefringent response:a form and a stress-related one.By refining this formalism,a multilayer approach is developed to imprint on demand optical rotation.Values up to+/-60°at 550 nm within an optimal 80μm thickness in silica glass are possible,corresponding to the highest value in a glass to date.These results provide new insights of circular-optical control in micro-nano optical manufacturing and open new opportunities for photonics applications. | Jiafeng Lu Jing Tian Bertrand Poumellec Enrique Garcia-Caurel Razvigor Ossikovski Xianglong Zeng Matthieu Lancry | 2023 | Light(Science & Applications)2023，12，3： | 0 |
